Hi Nathan, Thanks Sergey!

This is great. Before this disk, clondaq5 was the only machine where you could see the /data/hps drive, and so it was the only place you could do a replay of the data. I tried to get some plots for the 9am meeting this morning, while DAQ was off anyway, but basically could not because of all the hurdles. This will really help.

Best,
	Maurik
